Albert Barnes Commentary Psalms 119:149

"Hear my voice according unto thy lovingkindness: Quicken me, O Jehovah, according to thine ordinances." — Psalms 119:149 (ASV)

Hear my voice, according unto thy loving-kindness - According to your mercy; your goodness. Let that be the rule in answering me; not my deserts, or even the fervor of my prayers. We can desire no better rule in answer to our prayers.

O Lord, quicken me - Give me life; cause me truly to live. See the notes at Psalm 119:40.

According to thy judgment - Your law as a rule of judgment; your revealed truth, with all its gracious promises.
